The tarsal claws of the first and second pairs have a single small tooth near their middle part underneath ; on the other legs the claws were absent, probably broken off by accident. The falces are short, rather strong, directed backwards, and of a brownish orange-yellow colour. The abdomen is oval; its colour is pale yellow, with two broad, brown, nearly parallel, longitudinal, well-defined bands down the centre of the upperside, and a less well-defined marginal stripe of the same colour on each side ; taking the brown portions to be the ground-colour, there are thus three strong longitudinal yellowish stripes on the upperside-a straight one along the centre, and a curved one on each side; the underside has no markings, being of a uniform pale yellow; besides darker ones, the whole abdomen is thinly clothed with greyish hairs. The adult male (length If line) resembles the female in colours and markings ; the yellow stripes on the upperside of the cephalothorax are clothed with white hairs ; and the ocular area has the remains of a yellowish-grey pubescence. The palpi are short, their colour is a dull brownish yellow, and they are furnished with white and black hairs and bristles ; the cubital joint has a group of black bristles near its extremity on the inner side; the radial joint is rather shorter than the cubital, and furnished thickly with dark bristly hairs on the inner side ; the whole of the outer side is a little produced, and apparently terminates with two small, blunt-pointed apophyses, forming a small fork-like extremity (the hinder apophysis being the least strong, and of a dark brown colour) ; the digital joint is large, of an oval form, considerably exceeding in length that of the radial and cubital joints together ; its colour is yellow-brown, clothed with blackish bristly hairs, and tipped with grey ones ; the palpal organs are large, and consist of a nearly globular pale brownish-yellow corneous bulb, which extends backwards beneath the radial joint. The tarsal claws of the fourth pair of legs are very slender, and have several fine pectinations near and beneath the fore extremity; I was unable to observe those of the first and second pairs ; beneath the terminal claws in both sexes is a small dark scopula. The central yellow abdominal stripe in the male is much broader than the lateral ones, and has some very fine yellow points, issuing obliquely on each side, near its hinder extremity. These points represent the terminations of the ordinary angular bars, or chevrons, here obsolete. An adult male, and two adult females were found in Upper Egypt. It is a very distinct species, though allied to Attus lineatus, Koch, and A. bresnieri, Luc. ATTUS MEMORABILIS, sp. n. (Plate LX. fig. 110.) Adult male length 3 to 4| lines. Cephalothorax nearly double as long as broad, and of a flattened form ; its colour is yellow-brown, and of a much deeper hue on the hinder slope than on the sides, with a black margin slight! v fringed |
